Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Spritzgießen, insbesondere ein Kaskadenspritzgießverfahren, gemäß den Oberbegriffen der Ansprüche 1 und 2 sowie eine Vorrichtung zur Durchführung dieser Verfahren.The The present invention relates to a method of injection molding, in particular a cascade injection molding process, according to the preambles the claims 1 and 2 and an apparatus for carrying out these methods.
Beim Spritzgießen flacher und/oder langgestreckter Bauteile über einen einzigen Anschnittpunkt (Angussöffnung) ist es schwierig, die Kavität der Formwerkzeugs vollständig mit Schmelze zu füllen. Außerdem gelangt die Schmelze in die vom Anschnittpunkt entfernten Bereiche der Kavität bereits mit einer deutlich verminderten Temperatur, wodurch es zu Inhomogenitäten in der Struktur der gegossenen Bauteile kommen kann.At the injection molding flat and / or elongate components over a single gate (gate) it is difficult to get the cavity the mold completely to fill with melt. Also gets Already with the melt in the areas of the cavity remote from the gate point a significantly reduced temperature, which causes inhomogeneities in the Structure of the cast components can come.
Aus diesem Grunde ist es insbesondere beim Gießen langgestreckter und/oder flacher Bauteile bekannt, die Kavität der Formwerkzeugs über mehrere Anschnittpunkte mit Schmelze zu füllen (Prospekt der Fa. Incoe International ”Hot Runner Systems with Valve Gates”, veröffentlicht in der Zeitschrift ”Kunststoffe”, Heft 3, 1997). Hierbei besteht jedoch das Problem, dass die von den Anschnittpunkten ausgehenden Fließfronten der Schmelze irgendwo im Bereich zwischen benachbarten Anschnittpunkten aufeinandertreffen, wobei es zur Bildung von Bindenähten kommt. Solche Bindenähte stellen Schwachpunkte in den gespritzten Bauteilen dar. Außerdem sind die Bindenähte, je nach Material, Oberfläche oder Farbe, sichtbar, so dass solche Bauteile beispielsweise durch Lackierung nachbehandelt werden müssen.Out For this reason, it is especially when casting elongated and / or flat components known, the cavity of the mold over several To fill infeed points with melt (prospectus of the company Incoe International "Hot Runner Systems with Valve Gates ", released in the journal "Kunststoffe", Heft 3, 1997). However, there is the problem that the of the bleed points outgoing flow fronts the melt anywhere in the area between adjacent gate points clash, which results in the formation of sutures. Such tie lines are weak points in the sprayed components. In addition, are the tie lines, depending on the material, surface or color, visible, allowing such components, for example, through Painting must be post-treated.
Um die Entstehung solcher Bindenähte zu vermeiden, ist es bei Verwendung von Nadelverschlussdüsen bekannt (Prospekt der Fa. Incoe International, aaO), die verschiedenen Düsen zu unterschiedlichen Zeitpunkten zu öffnen, und zwar in der Weise, dass beispielsweise mit dem Einspritzen über eine erste Düse begonnen wird, und dann, wenn die von dieser Düse ausgehende Fließfront den Anschnittpunkt einer benachbarten Düse erreicht hat, diese öffnet. In entsprechender Weise wird mit dem Öffnen der noch weiter von der ersten Düse entfernten Düsen gewartet. Entsprechendes gilt, wenn der Einspritzvorgang über einen zentralen Anschnittpunkt beginnt, der von mehreren, vorzugsweise auf einem Kreisbogen um den ersten Anschnittpunkt liegenden weiteren Anschnittspunkten umgeben ist. Diese öffnen, wenn die Fließfront vom zentralen Anspritzpunkt die umgebenden Anschnittspunkte erreicht oder überschritten hat. Dieses Einspritzen in zeitlichen Abständen über mehrere Nadelverschlussdüsen wird als ”Kaskadenspritzgießen” bezeichnet.Around the formation of such weld lines To avoid it is known when using needle valve nozzles (Prospectus Fa. Incoe International, loc. Cit.), The different nozzles to different To open times in such a way that, for example, with the injection over a first nozzle is started, and then when the flow front emanating from this nozzle the Has reached the intersection of an adjacent nozzle, this opens. In the same way, with the opening of the still further from the first nozzle distant nozzles maintained. The same applies if the injection process via a central gate begins, of several, preferably on a circular arc around the first gate point further lying Surrounded by gate points. These open when the flow front of the central injection point reaches the surrounding gate points or exceeded Has. This injection at intervals over several needle valve nozzles will referred to as "cascade injection molding".
Das soweit beschriebene Kaskadenverfahren hat den Nachteil, dass beim Öffnen einer zweiten oder weiterer Düsen die Schmelze mit dem von der Spritzgießmaschine vorgegebenen Druck eingespritzt wird, der für alle Düsen gleich groß ist.The As far described cascade method has the disadvantage that when opening a second or further nozzles the melt with the pressure specified by the injection molding machine is injected for all nozzles is the same size.
Da beim Eintreffen der Fließfront von einer zuvor geöffneten Düse am Anschnitt einer benachbarten Düse die Schmelze der Fließfront bereits eine Abkühlung und einen Druckverlust erlitten hat, entstehen durch das explosionsartige Hinzutreten der unter vollem Druck stehenden Schmelze an der später öffnenden Düse unerwünschte Fließfrontmarkierungen. Dies kann vermieden werden, indem die später öffnenden Düsen nicht schlagartig, sondern langsam geöffnet werden und somit der anfängliche Einspritzdruck vermindert ist.There upon arrival of the flow front from a previously opened one Nozzle on Gap of an adjacent nozzle the melt of the flow front already a cool down and suffered a pressure loss caused by the explosive Addition of the melt under full pressure at the later opening Nozzle unwanted flow front marks. This can be avoided by the later-opening nozzles not abruptly, but slowly opened and thus the initial one Injection pressure is reduced.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine zur Durchführung des Verfahrens geeignete Vorrichtungen zu entwickeln, durch welche das explosionsartige Austreten der Schmelze an den zeitlich nachgeschalteten Anschnittpunkten in einer einfachen, kostensparenden aber doch zufriedenstellenden Weise vermieden wird.Of the The present invention is based on the object, a method and one for implementation the method to develop suitable devices by which the explosive release of the melt at the temporally downstream gate points in a simple, cost-saving but yet satisfying way Way is avoided.
Zur Lösung dieser Aufgabe wird ein Verfahren gemäß dem Oberbegriff des Anspruches 1 vorgeschlagen, welches die im kennzeichnenden Teil des Anspruches 1 genannten Merkmale aufweist.to solution This object is a method according to the preamble of the claim 1 proposed, which in the characterizing part of claim 1 features mentioned.
Dieses Verfahren kann in der Ausführung gemäß Anspruch 2 auch mit Vorteil verwendet werden bei Spritzgießanlagen mit nur einem oder mehreren Anschnittpunkten pro Kavität und Verwendung von Nadelverschlussdüsen, ohne daß ein Kaskaden-Spritzgießen erfolgt.This Procedure may be in the execution according to claim 2 are also used with advantage in injection molding with only one or more points of intersection per cavity and use of needle valve nozzles, without one Cascade injection molding takes place.

Vorteilhafte Ausgestaltungen dieser Vorrichtung sind durch die Merkmale der Unteransprüche 4 bis 7 beschrieben.advantageous Embodiments of this device are characterized by the features of the subclaims 4 to 7 described.
Das Verfahren und die Durchführungsvorrichtung gemäß der Erfindung erfordern keine Veränderung des Aufbaus der bekannten Spritzvorrichtungen. Der Eingriff beschränkt sich im einfachsten Fall auf die Einfügung von Bauteilen in eine der beiden Druckmittelleitungen zu den Kolben-Zylinderantrieben der Nadelverschlussdüsen. Das Verfahren gemäß der Erfindung ist sowohl für hydraulisch als auch für pneumatisch betriebene Nadelverschlussdüsen geeignet.The Method and the implementing device according to the invention do not require change the structure of the known spray devices. The procedure is limited in the simplest case on the insertion of components in one of the two pressure medium lines to the piston-cylinder drives the needle valve nozzles. The method according to the invention is both for hydraulically as well pneumatically operated needle valve nozzles suitable.
Auch dann, wenn es sich nicht um die Vermeidung der oben beschriebenen Fließmarkierungen, die beim Kaskadengießen auftreten, handelt, ist die Anwendung des Verfahrens gemäß der Erfindung von Vorteil, da sich beim Spritzgießen auch an den Anschnittstellen selbst infolge des explosionsartigen Einschießens der Schmelze unerwünschte Markierungen ausbilden können. Diese können ebenfalls durch das Verfahren gemäß der Erfindung und seine Durchführungsvorrichtung vermieden oder vermindert werden, und zugleich kann durch das Verfahren die Fließgeschwindigkeit der Schmelze günstig beeinflusst werden.Also then, if it is not about avoiding the above Flow marks, when cascading is the application of the method according to the invention of Advantage, as in injection molding also at the Anschnittstellen itself as a result of the explosive shooting of the Melt unwanted Can form markings. these can also by the method according to the invention and its implementing device avoided or reduced, and at the same time by the method flow rate the melt favorable to be influenced.
